Calculate the average speed of the athlete over the 2nd lap to the nearest m/s.
Step 1 - Find value for t using information given.
ti = 1 minute, 5.23s = 65.23 s
t2 = 2 minutes, 12.86 s = 132.86 s
t = t2 - t1 =
S,
s = 400 m
Step 2 - write down the appropriate equation, substitute
the required values, and round to the nearest m/s to get
the average speed.
S = vt
= v x
m/s
V=

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
